There are small holes in the cell wall that let nutrients, waste, and ions pass through. Those holes are called plasmodesmata. These holes have a problem: water can also be lost. But even when the plant cell loses water, the basic shape is maintained by the cell walls. So if a plant is drooping because it needs water, it can recover when water is added. So its pretty much so it can take in water.

there are pores simply because a cell needs to import/export packaged proteins and information from one cell to the other.
the proteins are packaged by the Golgi apparatus and shipped out of the cell. Proteins are also taken in either to be used or sometimes modified to perform a new function.

Is protoplasm made of the cell membrane?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
A researcher made an interesting observation about a protein used to build a cell's plasma membrane The final protein in the plasma membrane was slightly different from the protein made by the ER?
Golgi apparatus.
Can substances move in and out of the cell membrane?
Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane. I have made a link below to a diagram of the cell membrane to show some of these structures.
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
What are special structures in the cell membrane that allows material such as water and sugar to pass through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
What are cell membrane pores are made of?
Cell membrane pores are made up of protein.
What is the cell made of?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
Is protoplasm made of the cell membrane?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
What is the plasma membrane of a cell made of?
It is made up of protein and lipids
Is protein sythesis a function made by the cell membrane?
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
What is made up of a double layer of phospholipods and protein?
Cell membrane

What parts make up the cell membrane?
Most of the cell membrane are made up of proteins and phospholipids. The phospholipids make up the basic cell body, with tiny holes scattered around. It is not a solid piece. The proteins gather around the tiny holes and help move molecules in and out of the cell.
